E3D V6 Hotend clone always comes with bowden quick-connect fitting screw-in adapter. This is an issue if you are trying to use it direct drive extruder. Since there's no room for quick-connect adapter in these extruders it has to be unscrewed and short piece of bowden tube inserted into hotened. But it's a problem since there's now nothing to hold PTFE tube straight.
I've searched high and low for adapter, but to my shock there's nothing available.
So I just created a simple one. It screws in using large flat head screwdriver into top of hotend and then you just insert correctly cut PTFE tube...
I recommend you print two at a time since part is very small.
Print with something that can take more heat than PLA, but I don't think it really matters. Mine was printed out of Armadillo filament just because I had it loaded in my printer :)
